Re: zero width widgets

Ah, thanks. I had a DockLayoutPanel and was using a SimplePane as a place-holder in east, then later filling this SimplePane with a chat control. Perhaps there is a better way to dynamically replace DockLayoutPanel children. Anyway, I now tell the SimplePane to have width and height 100% (and a few other components, just to be sure), and it's laying out as I asked now.

Cheers.

I suspect this is from mixing layoutpanels with non-layoutpanels. By
and large, layoutpanels (anything with LayoutPanel as part of its
name) need to form an unbroken chain with a previous layoutpanel all
the way back to RootLayoutPanel. If you have an HTMLPanel or
simplepanel or other non-layoutpanel between layoutpanels, the inner
layoutpanel will be sized to zero unless you explicitly set its width
and height.
